US 12,363,319 B2 · Object-based context-based decoder correction

Abstract

Disclosed in some examples are methods, systems, and machine-readable mediums for utilizing context information to create decoding feedback information to improve decoder accuracy and/or performance. In some examples, the context information is from layers of a network stack above the layers in which the decoders are present. The context information may be or be based upon information about previously received and decoded data and/or information about the sender to provide decoding feedback information to the decoder that is used either to correct a previous decoding error or to inform the decoder on which of a plurality of decoding choices is more likely to be correct. This may increase decoding performance by decreasing errors and in some examples, reducing the complexity of choices by eliminating certain decoding possibilities and thus increasing decoder efficiency.

Dependent claims

A method for improving decoding performance of an image using object detection, the method comprising:

receiving an encoded image;
decoding a first portion of the encoded image using a decoder to create a first decoded image portion;
searching for at least one object in the first decoded image portion using an automated object recognition process;
determining, based upon the automated object recognition process, that an error is present in the first decoded image portion, and, in response:
correcting the first decoded image portion based upon the automated object recognition process to produce a corrected decoded image;
encoding the corrected decoded image to create a corrected encoded image;
decoding a second portion of the encoded image to create a second corrected decoded image, during the decoding, modifying at least one parameter of the decoder using the corrected encoded image, the parameter of the decoder comprising one of:
a path cost, a trellis, or a probability;
and
outputting the second corrected decoded image to a display device.
